<P>PROBLEM TO BE SOLVED: To provide a vertical axis wind mill in which a support frame body is built as a wind power dam, a vertical spindle with the multistaged arrangement of blades is arranged therein to concentrate the wind power into one position, the wind receiving area per setting area of the wind mill is far increased, on the other hand, the setting cost can be extremely reduced in size and weight. <P>SOLUTION: In the wind mill, a long blade 10 is arranged in one of the vertical spindles 5 stepwise arranged having lower and upper blades in an axis arrangement 4a of the support frame body 4 having the left side surface facing the vertical spindle 5. In the vertical axis wind mill 1, an inclined part 10a is formed to turn to the left at upper and lower ends in each blade 10. A plan phase of the blade 10 is successively displaced in the rotational direction from the upper step to the lower step by an equal angle, as a whole, the blade 10 is arranged around the spindle 5 at regular intervals in the plan. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
